Sure, here are the exact commands I ran to reproduce for
S390_UNWIND_SELFTEST. Note that I'm on x86-64 and cross-compiling for
s390:

1. Start from a minimal configuration:
'make ARCH=s390 CROSS_COMPILE=s390x-unknown-linux-gnu- allnoconfig'

2. Enter menuconfig:
'make ARCH=s390 CROSS_COMPILE=s390x-unknown-linux-gnu- menuconfig'

3. Set CONFIG_KUNIT=y

4. Set CONFIG_KUNIT_ALL_TESTS=y

5. Check '.config', and see that S390_UNWIND_SELFTEST is still disabled

The steps to reproduce for S390_MODULES_SANITY_TEST are the same, but
you also need to enable MODULES because of the additional dependency.

Thanks :)
Separately, I checked with Greg, and he says that:
1. it is a requirement to acknowledge tool usage, but
2. this patch (and others like it) shouldn't have the Fixes tag.

So I will resubmit this patch without "Fixes", but still acknowledging
the tool, see also:
